CEMENT BUILDING FORM.

Application filed April 7,

This invention relates to apparatusfor constructing cement buildings of all kinds and has for its object the provision of a novel form structure adapted to beset up at .the place where the building is to be erected so that when cement is poured in the walls and other elements will be formed.

An important object is the provision of a form structure in which the various parts are readily adjustable so as to build walls and other elements of widely different sizes.

Another object is to provide a form structure for constructing posts or pillars as well as overhead beams, any orall of which may be formed in conjunction with or separately from the wall structure.

An additional object is the provision of an arrangement of this character'which will be comparatively simple and inexpensive to manufacture, easy to set up and use, positive in action, eflicient and durable in service, and a general improvement in the art.

With the above and other objectsand advantages in view, the invention consists in the details of construction and arrangement of parts to be'hereinafter more fully described and claimed, and illustrated in the accompanying drawings in which:

Figure 1 is a perspectlve view of the form set up ready for constructing a corner of a wall,

Figure 2 is a. detail perspective View of a pair of the side plates,

Figure 3 is a perspective view of one of the transverse supports,

Figure 4 is a. perspective view of the closure structure for use at one end of a w all form,

Figure 5 is a perspective view showing an arrangement for constructing a post or column,

Figure 6 is a perspective view showing the forms for making beams.

Figure 7 is a perspective view of apartition structure which may be used in forming certain elements, and

Figure 8 is a perspective view showing an arrangement for forming a horizontal beam connected with a column or wall structure. Referring more particularly to the drawings, we have shown the wall forming structure as including outer and inner form members designated generally by the numeral 10 and of similar construction, each including platemembers 11 and 12 arranged inoverlapping relation and adjustably connected by 18 be bolted 0r nailed thereto.

bolts 13 which pass through slots 14. The ends of the plate members 11 and 12 are provided with outstanding flanges 15 which may be bolted or riveted, to the flanges of adjacent plate members in the same plane as shown ,at 16 or inla plane at right angles thereto as shown at 17. v

It is intended that the outer and inner form members be arranged in spaced relation and to maintain them at the proper distance apart, use is made of transverse braces 18 of angle bar construction notched or slotted at 19 for engagement upon the upper edges of the outer and innerplates or forms. Use is also made of vertically extending stays or posts 20 which may, in actual practice,

be simply lengths of 2 x & scantling and it is preferable that the transverse brace members In case it is desired to provide aproject-ion at one side of a. wall, use may be made of angular plates 21 bolted or otherwise secured to the flanges at the ends of the plate members 12 and having their outer portions over-lapping and slotted at 22 for the passage of clamping bolts. 23 whereby the necessary or desirable adjustment may be maintaine d.

. lVhenever it is desired to close theend of a wall formsuch as that abovedescribed, as for-instance at a doorway or window opening, use is made of plates 2tlbol ted to the outstanding flanges at the ends of the plates 12 and arranged inoverlapping relation, these plates 24L being formed with slots 25 for the passage of securing bolts 26 for maintaining an adjusted position.

In Figure 5 we have illustrated the form structure for constructing posts, pillars or columns of'rectangular form in cross section, and referring to this figure it willbe seen that we have provided right angularly shaped plate members 28 arranged in vertical position and in overlapping relation, the overlapping portions being slotted at 29 for the passage of securing-bolts 30fi'or main-' taining anadjusted position.

lVhenever it is desired to provide a column structure at the end, for instance, of a wall and to have the column structure formed integrally with tho wall'but spaced above the floor, use may be made of the slidably mounted overlapping partition plate members 31, shown in Figure 7 these plate members having depending flanges'32 adapted to be secured to the opposite sides of a post 1 "s lo or column mold; or against the oppositesides of a wall mold, in case such is desired, as

V i for instance when making window openings, Jth-ese plates having slots 33 through which members '35 and 36 slotted "at-37 for the acpass clamping bolts 3e for adjusting purposes, I 1

WVhenever itis desired to "form beams;

use is made of the structure illustrated in "Figure 6 in" which we have disclosed two interfitti'ng and 'slidaloly engaged trough com'modation of securing bolts 38.

I For forming-a" beamas the continuation ofthe' upper portion of a wall'projection such as is formed by the members 21, we make use of the beam molds just described or single trough members 39 disposed atthe upper ends of the members 21am held thereto j'as byangular brackets 40.-EXtension'side plates tl 'mayalso be provided in V 1 7 connection with the upper ends of the sides --'o-f the members 21 and connected with the ends of the trough Figure 8. V I I 4 V I From the foregoing it will be seen that molds are removed, Asthe mold members 4 are constructed of'metal it is evident that preferred embodiment of the invention, it

' "they 'should be durable and capable of prolo'nged use without bending, buckling or becomingothe rwi'se deranged. v

Wh11e'we have shown and described a s'hould'beunderstood that we reserve the right to makejsuch changes 1n the form; construction and arrangement ofparts as will not depart from the spirit "of the in-, 'vention or the scopeofthe 's'ubjoined claims.

Having thus described-the invention, we claim: s V 1. In a wall mold, outer and mner'mold all as illustrated in members each formed as a pair of longitudinally slidably adjustably connected plates provided at their outer ends with right angularly extending flanges adapted for connection with adjacent, mold members, up-

right supports located in spaced parallel 1 relation outwardlyand inwardly of the outer and inner mold members respectively, and

means connected with said uprights a n'den- V :gagrng the outer and inner members for 'maintalning-the latterin spaced relation','

said means comprising brace bars of angular formation in cross section adapted to be bolted to the uprights and having slots receiving theupper edges of the plates of the "outer a'nd inner. mold members.

2. Ina wall' mold, outer and innermold members each formed as a pair of longitu dinally slidably adjustably connectcdplates provided at their outer ends with right an- Lgularly extending flanges adaptedfo'r connection with adjacent mold memberaand i other vertically extending angular plate members having outstanding flanges adapted to besecuredto the first named plates, said angular plate members being laterally slidably adiustably connected. 7

"3; In "a wall mold, outer and inner mold members 'each formed as a painof-longi tudinally -slidably "ad-justably' connected plates provided at their outer ends with right angularly extending flanges adapted for connection with adj acent mold "members, i

and other vertically extending angular plate members having-"outstanding flanges adapted to be secured to the first-named plates,

said angular plate members being-laterally 'slidably adjustably connected; in combination with a trough-like beam mold detachably conneoted"with the upper ends of they assembled angular plate members.

In testimony whereof we ahix ours'ignw tures. V we JOHN A. CGMER V M. COMER-
